This little one I scored this weekend, in trip to a small town near me. It belonged to a guy who was a TV technician in the old days. He is also my wife's uncle. I paid US$ 10,00 for it. It's a Semp ( a brazilian brand ) from around 1967/68/69. He said it worked last time he plugged it. Right now the cord is separated from the TV, but I will test it later. The TV was in a room he has that is full of old stuff ( the old fan seem in one of the photos came from there also ). Sadly, he said that he had more old sets that went to dump recently. The one I saved was the last.

"Hope I haven't confused you too much, but basically you had the right idea"
It makes sense to me now that I know the space between the lines does actually increase. Thanks for the info.
Here's some pictures of a Zenith I've been working on, I got it working, it just needs some work done to the cabinet before I put it back together.

I kind of started this whole vertical size thing with the portholes. In the meantime I realized that the RCA TC-127 that I recently restored has a WIDTH selection switch. Kind of strange I think, but I'm glad its there. I had a bit of shrinkage on one side and that switch took care of it.

Regarding the 1B3 filament winding, the number of turns required to get the 1.4V needed by the tube filament depends on the design of the other windings of the flyback transformer. A specification called the Turns Per Volt Ratio is determined by the ratio of the number of turns in the primary winding to the AC voltage applied across the primary winding. Voltages induced in each secondary will be determined as a function of the Turns Per Volt Ratio. A transformer with a TPV of less than 1 is not uncommon, so a 1/2 turn secondary winding producing 1.4V is not unusual. Many color sets had low-ratio flyback transformers and produced 3.3V for the HV rectifier tube filament (3A3, 3B2, 3AT2, etc.) with single or 1-1/2 turn secondaries while deriving focus rectifier filament voltage for a 1X2, 1V2 or 2AV2 from a 1/2 or 3/4 turn winding.

Hello,

On the web I have found an old German advert for Graetz radio and television sets from the 1950's.

Go to

Hi Eckhard,

I couldn't open the movie...the space where it should appear remains "blank" in my computer.

Meanwhile, as I have shown my Semp TV set from the late 60's here comes an older model: a newspaper ad from January, 25, 1954 with the new 17 inch model from Semp.

Hi Captain Video,

try it with this link:

It is a Quicktime video.

Very cool. Nice TV sets they made...is this factory still in operation?

I will have to show this ad to my wife. She has German ancestors, and she actually speaks German. The only German word that I really learned so far is "schnapps" .

Hello There.
I just joined this Forum and i'm looking forward to talking about our old sets.
I own a few.
I have a Motorola VT71 and 3 50's vintage RCA B&W sets and an RCA CTC5 color set.
Also I have the Garod mentioned above which I have mostly working but TV sound is weak but I need to find a knob set for it.
I'd like to add a pic of it but there seems to be a problem with scripts on this page.

Anders

Hi. Usually if the pics won't load it's because they're larger than 195 Kb or 900x900, if you shrink them down it might work.

Here's my third RCA 721TS to date. First one, I sold on eBay after recapping and aligning. Held on to the second one and plan on holding on to this third one a while. This one has an electrodynamic speaker as every other 721TS that I've seen, but has a PM ion trap. I haven't recapped it yet, but have installed the safety devices and re-formed the electrolytics. Shown here is a flash photo of the set displaying a test pattern and another without flash.

Next two pics are of my Fada 799. The first is just the cabinet on display while the chassis is partially disassembled and waiting on a shelf for its repaired tuner to be reinstalled and recapping. Last pic is the set on display before disassembly.

Any tips on photographing sets with non-aluminized CRT so the flash won't wash out the picture and / or cabinet shows up well without flash?

Welcome to AK, Anders ! Nice t'have ya here !! quite a few of us who share the peculiar affliction for ratty-and otherwise-old TV sets...<grin>
